To all whom it may concern:

Be it known that I, DMCRA LIVINGSTON, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, inthecounty and State of New York, have'invented a new and Improved Cooling or Condensin Apparatus, of which the following is a fu l, clear, and exact description.

My invention relates more particularly to the cooling apparatus employed in conned I tion with motor'vehicles propelled by explosive-engines. It will be understood, however, that the invention has a wider field of usefulness and may be embodied in a condenser or in a heatin apparatus. In coolers of this character wa ls are provided having such a conformation and such a relation to each other as to produce when assembled conduits for the passa e of the water or other fluid to be cooled an passages at approximately right angles to the conduits for the .assage of atmospheric air orother cooling did.

In the manufacture of coolers for the stated purpose the walls referred to are in practice usually united by solder alone at their end edges because the walls have an irregular shape and their relation to each other is such as to make entirely impracticable the formation of such a jomt as a 1001 joint. The very severe strains to which the walls of such a form as to enable them to be assembled and interengaged with each other tion, in which similar re and with part cooler is subjected by the jarring of the vehicle produces a separation of the walls, and leakage of the fluid results.

The object of my invention is to provide at the joints.

he invention will be particularly described hereinafter and then defined-m the ap ended claims.

- Reference is to be had to the accompanying drawings, forming afpart of this specificaerence characters indicate corresponding parts in all the figures. Figure 1 is an elevation, partly in section broken away, of a cooling'or condensing apparatus constructed in accordance with my invention. Fig. .2 is an enlarged cross-section taken on the line 2 2 of Fig. 1. Fig. 3 re )resents an enlarged detail section taken on the line 3 3 of Fi 1. Fig. 4

are simply soldered in practice.

represents an enlarged detail section taken on view similar to the sec line 4 4 of Fig. 1. Fig. 5 is a cross-sectional tion shown in Figs. 3 I gather by a and 4, but illustrating a slight modification. Fig. 6 is a erspective view ofa portion of a cooler of a iflerent form and showing the application of my invention thereto, and Figs 7 is a longitudinal sectional view of the form of cooler shown in Fig. 6.

Referring more particularly to Fig. 1., walls A B are provided, forming the conduitsjlt) for the fluid. to be cooled and transverse passages 15 therebetween for the passage or air or the like, these walls being mountedin a frame 20 and the conduits communicating attheir top and bottom in practice with connesting-chambers 25 and 30. H I The detail construction of the cooler shown 79 in Fig. 1 is more particularly describedin Letters Patent granted to me August .16, 11904,

It will be observed that the walls are ,corrugatcd and at the ed es the juxtaposed walls 7 5 of two adjacent cond uits extend in close re: lation to each other, as indicated at theleft of Fig. 1. In describing the constrution shown in Fig. 1 I will refer to the walls es plates, since they are formed by platesyas 8o distinguished from complete tubes. It isefvident t liatwi th two adjacent lates formingithe walls and. serving to pro uce the conduits and passages referred to if the assen'iblage of the plates takes place before the plates are corrugated the conduit could not sub; sequcntly be corrugated, since the o posing plates would crush together. 'lhere oreitis the custom to corrugate the plates before, assembl ng; but the irregular formationof the 0 plates by ordinary methods precludes the pro duct-ionof an intcrengagemcnt or clocking of the plates with each other afterthe samehave been corrugated. Hence the meeting edges of the two adjacent plates forming a conduit 9 5 By my present invention I am enabled to produce an interlocking of the plates notwithstanding the latter are corrugated. 'lhus, referring to Figs. 2, 3, and 4, it will be Ice observed that a plate Alias at one end aplane edge u. and at the opposite end a hook or re turrnbcnd o. Sim larly a plate Bhas a plane edge 0 and at the opposite end a returnbcnd or hook I), and the hook on the plate A receives the plane edge on the plate B, and)" vice versa. Ilence notwithstanding that the plates are corrugated the two may be imposed one u )on the other and brought to l aterally-sliding movement until 1 1o the hook portions and plane engage as shown, thereby forming adouble lepjoint st the side edges.

Each corrugation forms three sides of a square, said sides being represented, respctively, by Figs. 2, 3, and 4. As Fig. 2 represents that side of conduit \vlii ch does not con tact with on. adjacent condui i, but the ntermediate portion, the plates A and B are brought-together at the median line of the conduit; The portions represented byFigs. 3 and 4, however, being the portions that co n tact when the respective conduits are assembled, are not brought together on the median line, but substantially in line with one side of the conduit. Thus in the section. Fig. 3 the plate A extends to the edge and is directly re: turned to form the hook portion o", the opposite edge a being plane. The plate B, on the contrary, is offset at its body portion, so that the hook portion 5') and the plane edge 5 lie pronouncedly at one side of the body portion, thus bringing the j oi nt between the plates A B close to the eneral plane of the plate A as distinguished om the plate E at this point.

In the section shown in Fig. 4, on. the contrcry,'it Will be observed that the reverse formotion occu s, since the pinto B is now the one that will contact With an adjncentconduit. Hence the plate B is directly returned to form the hook portion 5, it 'ie the body of the plate A is pronounccdly ofl'set'st its body portion, so that the hook portion a and the plane edge a lie pronouncedly at one side of the body portion, thus bringing the joint between the plates A B close to thegenoral plane of the plate B as distinguished from the plate A this point. y

it will further be observed in connection with the section shown in llig. 3 that at the edge Where the hook outh' plate B engages the plane edge of the plstdAit will be desirable thst the return member of said hock lie substantially in the plane with the plate A, so that when placed against the adjacent conduit both the s id hook portion and the said plate A will co ct n 3 id adjacent condui't, since the .t oct'ivcen adjacent conduits d by soldering. To brii'ig shout the necessary close contact, the plane edge a is depressed or set in very slightly, so

to permit there'turn portion of t c hook Z1 to lie about in the plane with the outer surfade of the body of the plate A. In the sec tion shown in Fig. 4 the opposite is true, the plate?) having its plane edge b slightly do pressed or set in to bring the hook portion a about in line 'With the plane of the outer sur- 3 face of the body of the plate B.

' The possibility of the separation of a joint between two conduits is rcther immaterial, 168 it Will not result in leakage, would a. oration of I, between co e.

sci 12eformed of two plates of similar formation placed in reversed position. Each plate A B is at one end directly returned on itself to form a. hook oortion a 11 while the opposite end of each plate is bent twice to produce the outWardly-projecting plane edge portions a l) at a pointoflset from the body.- In assembling the plates they are simply slid together in the longitudinal direction of the corrugations, as m the case of the previous construction, so that the hook portion of one engages the plane edge portionof the other, as indicated in said Fig. 5.

In forming plates in accordance with my invention I take essentially flat plates and by suitable dies turn overth'e hook portions, and in order that said hook portions may not be flattened against the body of the plate there is placed as acing-strin equal to the thickness of the p ate at suc i a distance from the edge as will enable the extreme edge to be returned to form the hook. The plate may then be corrugated to give it the required conformation to form the Well of a conduit, whereupon the spacing-strip i removed and the plates are then brought together the position shown in l i s. 2 to In Figs. 6 and 7 I love shown the application of my invention toe cooler in WlllClIl the wcllsere formed of tubestha-t is to say, the

wvells forming the four sides of an eirpassage are integral-Tend these tubes are given a reduced size in their body portion, as at C, While their relatively enlarged or ex and ed ends contact with each other, as s own clearly in Fig. 7, to produce between the contracted body portions the conduits O for the It will be understood that these figures are given to illustrate a Well-known form-10f cooler and that the invention is aplicable to coolers formed of tubular memers regardless of the special conformation given them to produce sir-passages and liouidconduits. On one end of each tube I form on each of the four Walls return-bends or hock portions c, and the opposite edges extend in plane form, as at c. In assembling these the tubes are reversed, so that at lane edge on ons will be engaged by e hooke portion on an adjacent tube, as will be clearlyv forming conduits for one fluid and'psssages for another fluid at about right angles to the conduits, adjacent Walls forming a conduit having their edges united by joints comprising an inwardly-disposed hock member on d and en dutsvsrdlydispcsed me nher onv the con1pcnion izsl-,'the relative poshltions of the hook members andthe members engaged thereby being reversed at the opposite edges.
